Embodiment Construction
[0053] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.
[0054] The present invention provides a cleaning solution for PCB developing tank, which comprises components and mass percentages as follows:
[0055] Ethylene glycol butyl ether 10-20%,
[0056] Emulsifier 15-30%,
[0057] Acid 20-40%,
[0058] The balance is water.
[0059] Among them, ethylene glycol butyl ether is a colorless and flammable liquid. Because of its chemical structure, it has two groups with strong solubility functions - ether bond and hydroxyl group. The former is lipophilic and can dissolve hydrophobic compounds, while the latter It is hydrophilic and can dissolve hydrophilic compounds, so it has a strong dissolving ability and is known as a "universal solvent". As the bulking agent of the PCB developing tank cleaning s...
